When our youngest son was still in school, we had people who stayed with him when Dave and I traveled. In order for those who were caring for him in our absence to get medical treatment for him if it was needed, we had to sign a legal document stating that they had the right to use our name on our son’s behalf—literally—to make decisions in our place.
That is what Jesus did for His disciples and, ultimately, for all who would believe in Him. He said that God will answer when we pray using His name. This is the authority you and I have been granted in His name.
His name takes His place—His name represents Him. When we pray in His name, it is the same as if He were praying. This privilege seems almost too wonderful to believe! But we can believe it because we have Scripture to back it up. So use the authority of Jesus’ name and put that power to work to overcome evil and bring the blessings of God to this world.
